If it was two teens having mutual sex I wouldn't have an issue.  

I canceled a commitment to some teens at my church last week to make it to the [canceled] meeting and pushed it to this upcoming Wednesday.

I will figure it out in that case.The other rudimentary 'formula ' is to not do things my teens or a basic handyperson can do. 

You could turn it into a revenue generating feature.Also, you might need to find a local teen to maintain it. 

I had one grandma and teen that I would love to rent to but it just would have taken too long.

Then the tenant calls us to come and find it- now their wasting of water is my fault and I get charged a maintenance call to chase ghosts... all because they have a teen that likes long showers... 

Just purchased a student rental on the east side of temple university campus. 4 bedrooms already teen at occupied by 3 young men.

Teen drivers think they know everything about driving, so mentors have to temper their enthusiasm to safe levels, if they do not develope dicipline they will crash, but hopefully live to learn.

I am most upset in her case that she has 2 late teen early 20s boys who do little if any work and live with her.

FYI, I purchased my first 4-plex when I was 19 ... a few weeks before my 20th bday but officially still in my teens.
